In cleaning the radiators and jackets of automobile and other internal combustion engines, it is customary to first place a quantity of scale loosening chemical inthe water i 5 system and to later forcibl flush thesystem with water flowing reverse y from the direction in which the water circulates in the cooling system, duringuse of the engine. While numerous guns and the like have been provided for directing the flushing water through the system under the influence of compressed air, the requisite amount of water pressure has been unobtainable with such contrivances. We have provided however, a novel device for attaining this end and such device has in practice proven much more eficient than pressure guns and the like which have heretofore been used. The present application seeks to'protect the novel construction from which the advantages flow.

The exact construction illustrated, has proven to be advanta eous from numerous standpoints, and whi e this construction is preferred and will be herein specifically described, it is to be understood that within the scope of the invention as claimed, minor variations ma be made.

The gist o the invention resides in the construction of the elongated casing 5 and associated elements. This casing is preferabl of semi-ovate shape, usually about ten inc es lon ,four inches wide and two inches thick, sai casing being cast in one piece, from aluminum or other desired metal. At its larger .end, the casing 5 is provided with a water-admitting hose connection 6 and at its smaller end is provided with a wateremitting hose connection 7. The interior of the casing is divided by a longitudinal partition 9, into a water passage and a relatively large water reservoir 11. The end of the passage 10 at the larger end of the cas- 60 ing 5, is in direct communication with the ting connection .7, leaving an opening 12 water-admittin connection 6, while the corresponding ven of the reservoir-11 is segregated from communication with said connec- -t1on 6. The

artition 9 terminates in inwardly space relation with the water-emitthrough which the passage 10 and. the res-- ervoir 11 are in d1rect.communication, at

the ends thereof toward said hose connection- 7. These ends of the passage 10 and reservoir 1.1 are in direct communication with the water-emitting connection 7 The casing 5 is preferably provided with substantially flat slde walls 13 and 14, and the wall 13 is provided near the end of the reservoir toward the connection 6, with an integral lateral enlargement 15 having an internal chamber. 16. In the present showing, the enlargement 15 projects partly into the reservoir 11 and partly to the exterior of the casing 5. l The outer end of this enlargement 15 is provided with a connection 17 for acompressed air line, and the inner end of said enlargement is formed with an opening 18 from the chamber 16 to the reservoir 11, and with an outwardly facing valve seat 19 around said opening. The side wall 14 is formed with an opening 20 in alinement with' the opening 18 and preferably carries a stufling box 21 at the outer end of said opening 20. A valve stem 22 asses snugly and slidably through the opening 20 and passes loosely through the opening 18, the inner end of said stem being provided with a valve 23 disposed in the chamber 16 85 and co-operable with the seat 19. A lmob 24 is secured upon the outer end of the stem 22, and a coiled compression spring 25 acts at one end against said knob and at its other end against the casing 5, saidspring serving to normally hold the stem 22 in the osition which it occupies when the valve 23 1s closed .against the seat 19. By inwardly pressing 2 team The free end of the hose 27 is provided with and a lower semi-ovate chamber adapted to an adapter 29 receivable in the upper hose fill with water from said 30 of an internal. combustion engine 31, when valved compressed air inlet mto passa e, and. s larger said hose 30 is uncoupled from the radiator end of said chamber.

- neck 32. A suitable plug 33 is provided to close this neck after removal of the hose 30 therefrom, and as the reverse flow of water which is to be effected through the cooling system of the en ine, will discharge through the conventiona filling neck 34 of the radiator, a shield 35 is (preferably empllgyed to direct this water ownwar ly in tures.

nt of said radiator. With the device con- 'nected with'the engine as shown in Fig. 1, 16 the water valve (not shown) controlling the hose 26, is opened, whereupon water ows through the hose 26, the casing 5 and the hose 27. Some of this water also fills the water reservoir 11 whose capacity may be substantially one pint. By now inwardly pushing upon the knob 24, the compressed air valve 23 is opened, with the result that the compressed air entering the reservoir 11, will forcibly discharge the water from the latter through the hose 27. This having been done, the valve 23 is allowed to close long enough for the reservoir 11 to refill,

whereupon said valve is again opened. The water is thus caused to successively gush or g lunge with unusual force, through the entire'cooling system of the engine, and any sediment, scale or the like loosened by the previously used chemical, will be effectively discharged. The compressed air is of course 88 at a much higher pressure than the water and hence while the air is discharging the water from the reservoir 11, the pressure holds back the water which would otherwise enter through the hose 26. This action is dis- 40 tinctly diiferent from a number of guns which have heretofore been employed, in which a stream of compressed air has been employed to mix with and hasten the flow of water through the entire clean-out device, more or less of a spray of water which is relatively ineflicient, being discharged by such guns.

What is claimed is A radiator clean-out device comprising a straight horizontal top wall, a downwardly bowed lower wall and opposed side walls jointly forming a semi-ovate casing, a water- -admitting hose connection in the larger end of said casing immediately under said top wall, a water-emitting hose connection in the smaller end of said casing immediately under said top wall, said connections being alined, a horizontal partition extending transversely throughout the width of the 0 casing and extending longitudinally from a point immediately below said water-admitting connection to a point spaced inwardly from said water-emitting connection, said partition dividing the interior of said casmg mto an upper straight water passage In testimony whereof we our HUBERT H.
